Abstract

The invention discloses a double front-end cover structure for a vertically installed motor, which includes a vertical motor, the vertical motor is arranged inside a tank body, the main shaft of the vertical motor is vertically arranged on the first end cover, and a thrust is arranged outside the main shaft Bearing, the inner ring of the thrust bearing is in contact with the retaining ring arranged on the main shaft, the outer ring of the thrust bearing is connected with the first end cover, and the first end cover is provided with a threaded slot hole inside, so The first end cover is also in contact with the auxiliary cover, and the auxiliary cover is provided with a round hole at the threaded slot hole of the first end cover, and the fixing bolt passes through the round hole and is screwed into the threaded slot hole. The advantages of the invention are: the invention can remove the auxiliary cover without separating the motor and the docking equipment, so as to observe the condition of the bearing and grease, and then decide whether it needs to be disassembled Machine maintenance, fundamentally reducing the unnecessary disassembly process.

Description

A vertically mounted motor with double front-end cover structure

technical field

The invention relates to the field of motors, in particular to an end cover structure of a vertical motor.

Background technique

Vertically installed motors have always been difficult to overhaul. Due to vertical installation, the front cover and bearings have to bear the weight of the entire rotor. After a long period of use, it is inevitable that the grease will deteriorate and even the bearings will be damaged. If the traditional single-layer end cover structure motor needs to be overhauled, the motor needs to be completely separated from the docking equipment, and then overhauled.

Contents of the invention

In order to solve the above problems, the present invention discloses a double front-end cover structure of a vertically installed motor.

The specific technical scheme is as follows:

A double front-end cover structure for a vertically installed motor, including a vertical motor, the vertical motor is arranged inside the tank body, the main shaft of the vertical motor is vertically arranged on the first end cover, and the outer side of the main shaft is provided with a thrust bearing, so The inner ring of the thrust bearing is in contact with the retaining ring arranged on the main shaft, the outer ring of the thrust bearing is connected with the first end cover, and the first end cover is provided with a threaded slot hole inside, and the first end cover The end cover is also in contact with the auxiliary cover, and the auxiliary cover is provided with a round hole at the threaded slot hole of the first end cover, and the fixing bolt passes through the round hole and is screwed into the threaded slot hole. The end caps are screwed together by movable bolts.

The center of the circular array of movable bolts coincides with the center of the circular array of fixed bolts.

The diameter of the round hole of the secondary cover is greater than the diameter of the fixing bolt.

The advantage of the present invention is: the present invention can remove the auxiliary cover without separating the motor from the docking equipment, so as to observe the condition of the bearing and grease, and then decide whether to dismantle the machine for maintenance, which fundamentally reduces unnecessary dismantling machine process.

Detailed ways

The present invention is specifically described below in conjunction with accompanying drawing, as shown in Fig. 1, Fig. 2, Fig. 3, a kind of vertical installation motor double front cover structure, comprises vertical motor 1, and vertical motor 1 is arranged on tank body 2 inside, vertical The main shaft 101 of the type motor is vertically arranged on the first end cover 3, and the outer side of the main shaft 101 is provided with a thrust bearing 4, and the inner ring 401 of the thrust bearing abuts against the retaining ring 5 arranged on the main shaft, and the The outer ring 402 of the thrust bearing is connected to the first end cover 3, and the first end cover 3 is provided with a threaded slot hole 301 inside, and the first end cover 3 is also in contact with the auxiliary cover 6, and the auxiliary cover 6 A round hole 601 is provided at the threaded slot hole 301 of the first end cover, and the fixing bolt 7 passes through the round hole and is screwed into the threaded slot hole 301. connected together.

The center of the circular array of movable bolts coincides with the center of the circular array of fixed bolts.

The diameter of the round hole of the secondary cover is greater than the diameter of the fixing bolt.
